Cubicolor was written by Rob Fulop while he was working Imagic, but the company refused to publish it. Nevertheless, he proceeded to sell it himself in a very limited amount of cartridges. He first sold these in the 80’s for $100 each, and then released the remainder in the mid-90’s when there was renewed interest. Most copies have a simple white label and are signed and numbered by Rob Fulop. It is unknown exactly how many copies exist, although it is believed to be less than 100.
Cubicolor is a truly interesting game that mixes the classic 'Rubik's Cube' with sliding puzzles. You have a grid made of up different colors, and on either side of the screen you will see a 3x3 pattern of different colors. The goal is to get the nine squares in the center of the grid (which form a 3x3 pattern) to match the same pattern. To do so, the player uses the joystick to slide the different colors around the grid by maneuvering a black space which represents the empty part of the puzzle. The game is complete when the player successfully gets that pattern replicated. There is no real method of scoring, nor is there a timer, so the only goal seems to be to get the pattern replicated in the fewest number of moves. One or two players can play simultaneously.
